MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Broadcast
Privacy Features:
  • ✓ Direct LoRa transmission (not via MQTT)
  • ✓ Custom channel: MediumSlow
  • ✓ Gateway node ID tracked
  • ✓ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
